Answer:
6.1
Step-by-step explanation:
If we are rounding at the 0 digit, we look at the next digit, which is 9
9 >= 5 so we need to round the 0 up to 1
6.099 rounds to 6.1
Answer:
6.1 is your answer
Step-by-step explanation:
The underlined digit (the tenth place) is 0. Look at the number in the place value directly right to it (hundredth place). It is a 9. Because 9 is greater than 5, round up.
6.099 rounded to the nearest tenth place is 6.1

if the domain of f(x) = x^2 + 1 is limuted to {0,1,2,3} what is the maximum value of the range?
Answer: 10
Plug in the given x values and see which result is the largest
Plug in x = 0 ---> x^2+1 = 0^2 + 1 = 1
Plug in x = 1 ----> x^2 + 1 = 1^2 + 1 = 2
Plug in x = 2 ----> x^2 + 1 = 2^2 + 1 = 5
Plug in x = 3 ---> x^2 + 1 = 3^2 + 1 = 10
The range is therefore {1, 2, 5, 10} which is just the set of possible outputs.
We see that y = f(x) = 10 is the largest output of the range if the domain is restricted to the set {0, 1, 2, 3}

Distinguish between the situations that can be modeled with a linear function, an exponential functions or neither
Answer:
Examples of linear functions would be relationships that represent a constant rate of change, such as 20 miles per gallon of gas. Exponential functions would be relationships that represent a growth or decay the increases or decreases by an exponential amount, such as a bacterial growth that doubles each hour. Examples of situations that would be neither linear or exponential would be absolute value functions or quadratic functions.
Step-by-step explanation:
Situations, or relationships between data, that can be modeled with a linear function must show a constant increase or decrease in rate. For example, we could control the rate of temperature in a water bath by two degrees every ten minutes. For exponential functions, these can be modeled in situations where there is a significant growth or decay of a material. For instance, the radioactivity of an element will decrease by one-half every year. This would represent an exponential decay. For other types of situations, such as changes in body temperature (absolute value) or the speed of a kayaker (quadratic), these would not be modeled using either linear or exponential functions.
A linear function can model constant rate of change, exponential function can model constant growth or decay, and some situations do not fit into these mathematical models.
Explanation:A linear function can model situations where there is a constant rate of change between two variables. For example, if the cost of a movie ticket increases by $2 for every additional hour of the movie, you can represent this relationship with a linear function.
An exponential function can model situations where there is constant growth or decay. For example, if the value of an investment doubles every year, you can represent this relationship with an exponential function.
There are situations that cannot be modeled with either a linear or exponential function. For example, unpredictable events or situations with multiple complex factors may not fit into these mathematical models.

Paws at play made a total of $1234 grooming 22 dogs. Paws at Play charges $43 to groom each small dog and $75 for each large dog.
a. Write a system of equations that can be used to determine the number of small and large dogs that were groomed.
b. How many large dogs did Paws at Play groom?
Answer:
Answer (a):
s + l = 22 ... (i)
43s + 75l = 1234 ... (ii)
Answer (b)
9 large dogs.
Step-by-step explanation:
Paws at Play made a total of $1234 grooming 22 dogs.
Paws at Play charges $43 to groom each small dog and;
$75 for each large dog.
Let the number of small dogs be 's'
And the number of large dogs be 'l'
A system of equations will be:
s + l = 22 ... (i)
43s + 75l = 1234 ... (ii)
Solving this set of simultaneous equations by elimination, we simply multiply (i) by 43 to get;
43s + 43l = 946 ... (i)
43s + 75l = 1234 ... (ii)
Subtracting (i) from (ii) we get;
32l = 288 , l = [tex]\frac{288}{32}[/tex] = 9
So there are 9 large dogs.

Which expressions are equivalent to (5⋅x)⋅3 ? Drag and drop the equivalent expressions into the box.
3⋅(5⋅x)
5⋅3+x⋅3
5⋅(x⋅3)
15x
5⋅3⋅x⋅3
Answer:
3⋅(5⋅x)
5⋅(x⋅3)
15x
Step-by-step explanation:
As the values are inside the brackets, it does not matter what side the (x3) is on, so 3⋅(5⋅x) is equivalent.
Multiplying the contents of the brackets in the third one (x * 3) by 5 gives the same value as 3 * (x * 5) so 5⋅(x⋅3) is also equivalent.
On multiplying the brackets out:
5 * x = 5x
5x * 3 = 15x
So 15x is also equivalent.

What is the zero in the quadratic function f(x)= 9x^2-54x-19?
Answer:
6.33... and 0.333...
Step-by-step explanation:
The quadratic formula is
[tex]x=\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex].
It is important because while some quadratics are factorable and can be solved not all are. The formula will solve all quadratic equations and can also give both real and imaginary solutions. Using the formula will require less work than finding the factors if factorable. We will substitute a=9, b=-54 and c=-19.
[tex]x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}\\x=\frac{-(-54)+/-\sqrt{(-54)^2-4(9)(-19)} }{2(9)}\\x=\frac{54+/-\sqrt{2916+684} }{18}[/tex]
We will now solve for the plus and the minus.
The plus,,,
[tex]x=\frac{54+\sqrt{3600}}{18}\\x=\frac{54+60}{18}\\x=\frac{114}{18}\\x=6.3[/tex]
and the minus...
[tex]x=\frac{54-\sqrt{3600}}{18}\\x=\frac{54-60}{18}\\x=\frac{-6}{18}\\x=-0.333...[/tex]

If 2/3 of the 600 seeds sprouted, how many seeds did not sprout?
By calculating 2/3 of 600, we find that 400 seeds sprouted, which means 200 seeds did not sprout.
Explanation:To determine how many seeds did not sprout, we start by calculating the number of seeds that did sprout. Given that 2/3 of the 600 seeds sprouted, we multiply 600 by 2/3:
600 × (2/3) = 400
So, 400 seeds sprouted. Next, we subtract this number from the total number of seeds to find out how many did not sprout:
600 - 400 = 200 seeds
Therefore, 200 seeds did not sprout.

A target is made of a blue square inside of a red square. The blue square has an area of 64 square units, and the red square has an area of 196 square units.
Assuming it hits the target, what is the probability that a dart will land in the blue region?
A.
0,25
B.
0.33
C.
0.67
D.
0.75
Answer:
B. 0.33
Step-by-step explanation:
The probability will be given by the amount of space in the target area, blue, compared to the total amount of space, the red square.
The size of the blue square is 64 and the size of the red square is 196; this gives us a probability of
64/196 = 16/49 = 0.3265 ≈ 0.33.
The required probability that a dart will land in the blue region is 0.33. Option B is correct.
Given that,
A target is made of a blue square inside of a red square. The blue square has an area of 64 square units, and the red square has an area of 196 square units.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Total sample space = 196
Total favorable space = 64
The probability that a dart will land in the blue region is given as.
probability = 64 / 196 ≈ 0.33
Thus, the required probability that a dart will land in the blue region is 0.33. Option B is correct.
